# BPD Tracker vs Quill

The clearest difference is rating: Quill at 5.0 against BPD Tracker's 4.1. Quill also leads on update cadence (every 4 days vs every 6 weeks). BPD Tracker's advantage is ratings volume (60 vs 1) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BPD Tracker sells 15 in-app purchases, starting at $4.95 per month and Quill sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quill holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: BPD Tracker has 60 ratings behind it against 1, so its average is the more settled of the two.

BPD Tracker ships an update every 6 weeks, Quill every 4 days. The most recent releases landed on October 25, 2026 and October 13, 2026 respectively.
